S7-200 connection

hi everyone ,,,,,
how can i connect PLC S7-313C with S7-224 cpu via MPI connection? does this need SIMATIC MANAGER or microWIN ?,,,,,

S7-200 is programed in MicroWin. I have always connected using PPI. I do not think you can program thru and MPI but there are others who can give you a more definate answer on that.

Connection

Hi

MPI for Microwin,

transmission rate standart for S200 is 19,5 Kbps.

If to set higher you will not be able to conect with PPI cable

Hello Moody;
Follow this link to the Siemens support webpage; here is a FAQ showing how to use functions in the S7-300 (X_PUT and X_GET) to read and write data to a S7-200 CPU [so the programming for the comm functions is done in Step 7 Simatic Manager]:

Hope this helps,

Click to expand...

Are you wanting to network your PLC's?

yes i want building a network as i mentioned
i want the hardware configuration as well as software configuration (dchartier)
and i need to use microWIN ??

Hi there
I think EM 277 will do. I have used this to connect 300 and 200 with profibus. But if you see technical specification of this EM277 its written that it supports both MPI and profibus.

* For connection of the S7-22x to PROFIBUS DP (as slave) and MPI
* Can be simultaneously operated as MPI slave and DP slave
* Transmission rate max. 12 Mbps
* Can be used with CPU from version 6ES7 22x-xxx21-xxxx


I cant figure it out how I can connect Em277 with MPI though. Because in Net pro if I try to connect EM 277 module to MPI network it comes up with the message:


"You have to either select a DP module with a DP master system or DP slave in order to place a DP slave"

Bold part sounds like if you dont have DP port then you need to use DP Module CP 342-5 with 313.

Would like to know how EM277 can be connected to MPI n/w.



Edit:It seems that if you want to connect 200 to 300 then simply connect MPI port of 300 to Port 0 or 1 of 200. Make sure that this port of 200 has baud rate of 187.5Kbps. And then use X_PUT and X_GET instructions in 300 to communicate.No need of EM277.

ok manmeet
but what is the instruction that i have to use in microWIN to communicate with the S7-300?
